Ongororo yepasi rose yakawana chikonzero nei vamwe vanhu vanodya chikafu chine mafuta akawanda vachiramba vari vatete, asi vamwe vachitutira uremu.

Chidzidzo ichi, chakatungamirirwa muAustralia neMonash Obesity uye Diabetes Institute (MODI) paMonash University, chakawana kudya kwemafuta akawanda kunoita kuti masero europi ave insulated kubva mumuviri kudzivirira zviratidzo zvinokosha, izvo zvinoudza muviri kuti urege kudya uye kupisa simba., kubva pakusvika kuuropi zvakanaka.

MODI director uye weAustralia Life Scientist weGore Muzvinafundo Michael Cowley vakati pane zviviri zvakajeka zvakabuda kubva pane zvakawanikwa.

"Takaona kuti kudya kwemafuta akawanda kwakakonzera kuti masero europi avharwe kubva mumuviri, zvichiita kuti masero asakwanise kuona zviratidzo zvekuzara kuti arege kudya," Purofesa Cowley akadaro.

"Chechipiri, kuvhara kwacho kwakagadzirawo imwezve dambudziko pakuti muviri hauna kukwanisa kuona zviratidzo zvekuwedzera simba rekushandisa uye kupisa makorikori / kilojoules."

Tsvakurudzo yakaratidza kuti masero ekutsigira muuropi akakura kukura mukudya kwemafuta akawanda. Izvi zvakadzivirira masero europi enguva dzose (iyo melanocortin system kana POMC neurons) kubva pakubatana nedzimwe nzira dzeneural, dzinotarisa kudya uye kushandiswa kwesimba.

Muzvinafundo Cowley vakati zvakawanikwa muongororo zvinopa chinongedzo chakakosha mukugadzirisa denda rekufutisa.

"Idzi neuronal circuits dzinogadzirisa maitiro ekudya uye kushandiswa kwesimba uye inzira inowanzoitika muuropi. Masekete anotanga kuumba pakutanga kwehupenyu kuitira kuti vanhu vave netsika yekufutisa kunyange vasati vadya kudya kwavo kwekutanga, "Purofesa Cowley akati.

Kudya kudya kwemafuta akawanda kunokonzera kuwedzera kwe "insulation" mumasero etsinga, uye zvinoita kuti zvive zvakaoma kuti uropi hubatsire munhu kuderedza uremu.

"Vanhu vakafutisa hazvirevi hazvo kuti vanoshaya simba rekuita. Uropi hwavo hauzivi kuti vachengeta mafuta akawanda zvakadii, saka uropi hauudze muviri kuti umire kuwedzera mafuta. Zvadaro, kukwanisa kwemuviri wavo kuderedza uremu kunoderera zvakanyanya."

Muzvinafundo Cowley nemumwe muongorori weMODI Dr Pablo Enriori vakabatana naSachigaro Wekutsvagisa uye Purofesa weComparative Medicine uye Purofesa weNeurobiology Tamas Horvath nechikwata chake paYale School of Medicine muUnited States, pamwe nezvikwata zvesainzi muCincinnati, New Jersey, Mexico. uye Spain.

Kwenguva yemwedzi mina, vatsvakurudzi vakatarisa kudya uye kuumbwa kwemuviri wemapoka emakonzo nemakonzo uye vakaona kuti avo vane neural predisposition yekufutisa vakawana 30 per cent yakawanda uremu kana ichienzaniswa nezvikamu zvitanhatu kubva muzana zveboka rine masero anodzivirira kufutisa..
